A solution to Ps4 DNS Error NW-31247-7 :

Although the problem seems to be simple the solution may be a little hard to implement as there may be different reasons which are causing this PS4 DNS Error. Make sure to check them one by one to have a maximum chance of solving this. As you can see from the comments from the above YOutube videos too that many have suffered from ps4 DNS error nw-31247-7 but most of them have solved these problems with these methods.

1. Restart The Router

While it may hear way simpler but restarting the router may be the first thing you want to do in these causes as sometimes the router itself cannot giver a proper id to the PS4 device thus resulting in the error. A simple restart may fix the error but if complex we may have to take other actions.

2. Assigning DNS of PS4 Manually

To manually assign DNS to the ps4 just follow the steps below:

  • Go to play station  settings > network > set up internet connection > LAN cable / Wifi > custom.

(Now you can manually change the settings of the network. Just follow the instruction given on the PS4 screen).

  • Accept the options as you wish till you get DNS settings. Like custom >Ip Address (automatic) > DHCP hostname (Do not specify) > DNS settings
  • Now in the DNS settings use Manual option and put in (Google’s Public DNS server 1) as Primary DNS (Google’s Public DNS server 2) as Secondary DNS

OR,                                                                                                                                                                     (Open DNS server 1) as Primary DNS (Open DNS server 2)  as Secondary DNS

  • Now follow till the end like DHCP hostname (Do not specify) > DNS settings (manually)> MTU server (Automatic) > Proxy Server (Do not use) and click on the internet connection to check everything is working correctly.

3. Setting the Router to use DHCP

A DHCP allows you to manage your IP, DNS, default gateway, etc on a network. Setting the Router in DHCP mode is the best option as it can assign the IP according to the device so that there is no conflict between the devices with the same Ip address which helps to forward your port also. When DHCP is enabled it assign your device with unique static IP which only changes over a few days/weeks or even months. If two devices are assigned to the same Ip than there will be conflict in the network and the PS4 server won’t be able to send the required data to the necessary client thus resulting in the PS4 DNS error nw-31247-7.  You can see the article on how to change the router to DHCP mode or static mode to use DHCP on your network.

4. Calling your ISP

Well if you can’t change the DNS your self and still facing this error then the best solution will be to contact your ISP ASAP about this matter. They will either give you better DNS, open your ports for PS4, etc and may solve the problem but I have found that many of the ISP won’t solve this problem at all.

5. Resetting your ROUTER to the default configuration (risky)

If none of the above works than resetting the router may be a risky but helpful solution. Before resetting your Router make sure that you know your default password of the wifi so that you can connect to the wifi after you have reset your router.
